For engineers reviewing the R5F72375ADFP#H0 datasheet, R5F72375ADFP#H0 pinout, R5F72375ADFP#H0 application, or R5F72375ADFP#H0 equivalent, key selection criteria include CAN interface compliance, Flash endurance (100K write/erase cycles), operating temperature range (−40°C to +105°C), and AEC-Q100 Grade 2 qualification for automotive use.

Technical Context

The R5F72375ADFP#H0 implements the SH-2A CPU core with 32-bit integer execution, 16 KB on-chip RAM, and a multi-layer bus architecture supporting concurrent access to Flash, RAM, and peripherals. It integrates a Clock Pulse Generator (CPG) with PLL, power management modes (HALT, STOP, and SLEEP), and an Interrupt Controller (INTC) with 128 interrupt sources and priority levels.

Peripheral integration includes a 16-channel 12-bit ADC with hardware-triggered sampling, dual SCI modules supporting asynchronous and LIN 2.1 protocols, one I²C interface, and a full CAN 2.0B controller with message objects and FIFO buffering - all accessible via dedicated DMA channels managed by the Data Transfer Controller (DTC).

FAQ

What is the maximum operating frequency of the R5F72375ADFP#H0?

The R5F72375ADFP#H0 operates at a maximum CPU frequency of 64 MHz, achieved using its on-chip PLL with external crystal input (typically 8 MHz). This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and automotive range (−40°C to +105°C), with timing validated per Renesas' hardware manual Rev. 2.00. The R5F72375ADFP#H0 maintains instruction throughput and peripheral synchronization at this rate without derating.

Does the R5F72375ADFP#H0 include a CAN controller, and what version does it support?

Yes, the R5F72375ADFP#H0 integrates a single CAN 2.0B-compliant controller with 32 message objects, programmable acceptance filtering, and FIFO buffering. It supports both standard (11-bit) and extended (29-bit) identifier frames, bit rates up to 1 Mbps, and automatic retransmission. This implementation meets ISO 11898-1 requirements and is fully documented in the SH7237 Group Hardware Manual. The R5F72375ADFP#H0's CAN peripheral is functionally identical to that in the R5F72376ADFP#H0.

What package type and pin count does the R5F72375ADFP#H0 use?

The R5F72375ADFP#H0 uses a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm pin pitch. This package is RoHS-compliant, rated MSL 3, and shares mechanical and thermal characteristics with other SH7237 Group devices such as the R5F72374ADFP#H0 and R5F72376ADFP#H0. Pin assignments - including dedicated CANH/CANL, SCI, and ADC terminals - are fixed and documented in Section 1.4 of the SH7237 Group Hardware Manual Rev. 2.00. The R5F72375ADFP#H0 is not offered in QFP-100 or BGA variants.

Is the R5F72375ADFP#H0 qualified for automotive applications?

Yes, the R5F72375ADFP#H0 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C), covering thermal cycling, HTOL, ESD, and EMC testing per automotive standards. It is intended for non-safety-critical automotive applications including body control modules, junction boxes, and HVAC controllers. Renesas specifies this qualification explicitly for the SH7237 Group in product change notices and datasheet supplements. The R5F72375ADFP#H0 does not carry ASIL certification but provides foundational features (ECC Flash, watchdog timers, clock failure detection) usable in ASIL-B decomposition strategies.

What development tools support the R5F72375ADFP#H0?

The R5F72375ADFP#H0 is supported by Renesas' e2 studio IDE, CS+ (formerly High-performance Embedded Workshop), and the E2 emulator Lite. Debugging uses the on-chip JTAG interface (pins 139–142), and flash programming is enabled via on-chip bootloader accessible through SCI0. Renesas provides device-specific drivers, HAL APIs, and example projects for CAN, ADC, and SCI in the Synergy Software Package (SSP) v1.7.0+. All tools target the exact R5F72375ADFP#H0 silicon revision and require no hardware adaptation.
